While obvious bulging capacitors are easily identifiable, he discusses the need for an ESR meter and uses a kit-built model to test capacitors that do not have any visual signs of damage.

[Peter Demchenko] wanted to use a low power TS555 in an ESR meter design. The problem is, he needed to handle significant current sink requirements for cases where the capacitor under test had a ...

Exxelia, the global leader in high-performance passive components and subsystems for extreme environments, introduces four ...

External, discrete capacitors have non-idealities that can be critical. There is a parasitic Effective Series Inductance (ESL), and a parasitic Effective Series Resistance (ESR). Both ESL and ESR ...

Panasonic Industry Europe has announced substantial improvements in its hybrid capacitor production capacity, which it says ...
